EK and Dubai is what you make of it. So if you decide to go and live in the company villa, surrounded by your bitter colleagues 24/7, read PPRuNe all day and then whinge about it in the flight deck, wife on facebook club etc, then YES you are going to be miserable here. Or... you distance yourself from all of that, live somewhere nice (not in EK accommodation), make the most of what Dubai has to offer, have a good set of friends who have similar aspirations to yourself etc, go to work, have a good time, go home and leave it at that.... then you will enjoy it here.
